It may be that you are trying to move your DB from on premise to Azure and using ALTER DATABASE command. Once you make the metadata change using ALTER DATABASE and then move the physical file to AZURE, the DB fails to come online with the following error message:
2014-05-15 04:31:59.370 spid26s Error: 5120, Severity: 16, State: 142.2014-05-15 04:31:59.370 spid26s Unable to open the physical file "https://ifxx.blob.core.windows.net/iftpoc/xxx.mdf".

The physical file name "https://ifxx.blob.core.windows.net/ifxxc/xx_log.ldf" may be incorrect.
There are two issue here:
1. When you have moved the files, the files have been moved as block BLOB and not as page Blob. To remove this restriction, you have to make use of API mentioned by PG team to move the files.
2. There are already files with the same name on the blob container which we have created.
The best option to move the database is to take a backup and then restore it with the move command:
USE master; GO; RESTORE DATABASE TestDB3Restore FROM DISK = 'C:\BACKUP\TestDB3Restore.bak' WITH REPLACE, MOVE 'TestDB3Restore' TO 'https://ifxx.blob.core.windows.net/iftpoc/TestDB3Restore.mdf', MOVE 'TestDB3Restore_log' TO 'https://ifxx.blob.core.windows.net/iftpoc/TestDB3Restore_log.ldf'; GO;
Happy Learning & Troubleshooting!!
